1. Since Ben is not able to move his right arm, the primary motor cortex of the left cerebral hemisphere must be affected by the stroke.
2. The dentist is blocking the fifth cranial nerve i.e. trigeminal nerve. More specifically, the dentist is blocking the inferior alveolar nerve branch of the mandibular branch of the trigeminal nerve.
3. The cause of death in some patients is the host response to the organisms that cause meningitis. The pathogens and the inflammation of the meninges activate the microglial cells to release large number of inflammatory intermediates, oxidative radicals, etc. This causes chemical injury to the brain, ultimately leading to cerebral edema. The pressure from the edema exacerbates brain injury, causing neuronal death. This may result in coma and death.
